Question

how to graph f(x) = 2/3x - 1/2

Please help me. Really need some help here.

Answer 1

Set x=0 and y=0 to find both y-intercept and x-intercept
y=2/3(0)-1/2
y=-1/2
0=2/3x-1/2
2/3x=1/2
x=1/2*3/2=3/4

Answer 2

But can you use the formula m=rise/run here?

Answer 3

\[y=slope (rise/run)x +b\]

Answer 4

So will the graph still be the same if I use the formula you have given and when I solve by substituting x and y by O in finding the x and y intercept?

Answer 5

yes absolutely

Answer 6

Ahhh.. Okay, thanks :)
